Be it known that I, ABRAM E. SMIT a citizen of the United States,residing at Huguenot Park in the county of Richmond and State of NewYork, have invented certain new and useful Improvementsin Tank Cars, ofwhich the following is a specification. a My invention relates to tankcars, and particularly of that character or type generally employed forrailway transportation of liquids inbulk, and which comprises ahorizontally disposed cylindrical tank supported upon an .underframewhich, in turn, is mounted on wheeled trucks. Theinvention consists inthe improvements to be more fullydescribed hereinafter andthe novelty ofwhich will be particularly pointed out and distinctly claimed. l l havefully and clearly. illustrated a preferred embodiment of my invention inthe accompanying drawings to be taken as a part of thisspecificationyand wherein Fig ure 1 is a view in side elevation of oneembodiment of my invention and so much of a car structure asisinecessary to illustrate the application of the invention. thereto,certain parts of the oar structure being omitted for the sake ofclearness; Fig.2 is

view showing the connectionof Fig. 2 in end elevation, and thelpreferredlocation of the same relative to the understructure, and Fig. 4 is adetail view in side elevation of the connecting means shownin Fig. 2.

Before describing my invention in detail, I would state that while haveshown the same applied to a well known type of car underframe, I wish itunderstood that my invention is not limited to this type of underframeas it contemplates within its scope any type of'underframe to which itmay be applicable. r l y v 1 My present application is division of myprior applicationSerialNo. 447,178, whlch was filed in theUnitedStateslatent Office on or about February 23,'1921.

Referring to the drawings by characters of referencefl designatesgenerally the underframe or understruoture of a well-known Divided inthis application filed June 7 type of car, the same being shown asconsist ng of a center sill or structure 2 made up of structural ironconsisting preferably of channel members 'or girders arranged with theirbody portions or webs 2' spaced from each other in vertical parallelplanes andwith the side flanges3, 4, thereof ex tending outwardly fromthe up er and lower edges of the webs. The vertica girder membersdescribed are connected by upper and lower horizontal plates 5, 6,resting respectively on the'outer faces of the flanges 3, 4, and securedrigidly thereto by means of rivets passing through the side edges ofsaid plates and through said'fianges, whereby a rigid girder structureis provided. The said center sill extends preferably the entire lengthof the car and is connected at its ends to end sills 7 in anywell-knownmanner i(not,shown). At, its opposite ends the underframe is providedwith suitable bolsters 8, which may be of any suitable commercial type,for example, ajbuilt up, structure con sisting' of flanged verticalmembers 8 secured at their inner ends to the center sill rivets or othersuitable means, and at their outer ends to the longitudinal side members9 said'vertical members 8 being connected by upper and lower-horizontalplateslO, 11.

The under-frame is supported, in any suitable manner, upon wheeledtrucks (not shown) carrying running wheels 12 adapted to travel 'upon arailway track.

l3 designates a tank body which may be jor any suitable construction,the same being preferably cylindrical in form, and arranged overthejunderframe and adapted to rest on saddle blocks 7 which are in turn.seatedin saddlebrackets"7 secured'to th bolster 8 (one of said saddlesbeing shown.

in each of Figs. 2 and 3), the longitudinal cated at the center portionoi the tank body so as to act as an anchor for that portion and serve topermit longitudinal expansion and contraction of the opposite endportions of the tank body relative to said connection. The details ofthe construction by which the tank body is secured to the undertrame aremore fully disclosed in my prior application above referred to, to whichreference is made for further details. Briefly, the constructioncomprises a plate secured to the underirame and secured to the tank bodyon both sides thereof. In Figure 1, the securing portion of the plate isshown on one side at 22}, the same being riveted to the tank body asat24:.

I provide improved means for securing the endportions of the tank bodyto the underframe, so as to limit or prevent vertical and sidewisemovement of the tank body relative to the underframe, but permittinglongitudinal movement oi the said end portions due to temperaturechanges. This connection in its preferred embodiment comprises pairs ofvertically disposed members 26, and located inside of the brackets 7 asbest shown in Fig. 3, the members of each pair being arranged,respectively, in spaced relation, and in parallel planes extendingtransversely of the underframe, and each of said members being connectedto the underframe by a base flange 27 rigidly secured by rivets 28 tothe cover plate 10 forming part of the bolster structure heretoforedescribed. These pairs of members 26 are located, respectively, onopposite sides of the longitudinal axis of the under-frame, as clearlyillustrated in Fig. 2 of the drawings. Secured to the under portion'ofthe tank body at points over the bolsters, are depending ears or lugs29, each of which is integral with a securing member in the form of aflange 30, which is rigidly secured by means of rivets 31 to the tankbody, whereby each of said members 29 is rigidly'and immovably connectedto the latter. The arrangement is such, there fore, that while the endsof the drum are free to move longitudinally, they are prevented 'frommoving either laterally or transversely. Each member 29 projects intothe space between a pair of the members 26, and is of a thickness lessthan the width of said space, as clearly illustrated in Figs. 1 and 2,so that't-he member 29 may have sufficient movement or play between theinner vertical faces of said members 26 when the tank body expands andcontracts lengthwise of the underframe relative to the centerconnection. Each of the members 529 is secured to its pair of securingmembers 26 by means ofa cross bolt or pin 32 extending through aliningopenings in said members 26 and that portion of the member29 arrangedbetween said members 26 so that the member 29 may move longitudinally ofthe un- ,relative to the underframe.

dertrame, as heretofore described, but is held against verticalmovement. thereby preventing vertical movement of the tank body The pins32 are each preferably in the term ol :1. headed bolt. the head 3?, ofwhich is located on the outer side of one of the members 20, and whichbolt is held in place by means oi cotter-pin Ill on the opposite end olsaid pin from the head and the outer side of the other member 26 of thepair. The hole in the member 29 through which the bolt projects is madelarge enough to permit free longitudinal movement of the tank body. Thisconnection is not only simple and effective in structure, but eliminatesthe necessity of tank bands commonly used in tank car structure, and thedisadmntages of which are well-known.

hat I claim and desire to secure by Letters Patent of the United Statesis:

5. In a tank car, an undertrame comprisllO lug longitudinally of theunderframe, and

prevent movement vertically thereof.

In a tank car, a tank body, an under- :frame comprising a transversebolster, saddles mounted one on eitherend of the bolster for supportingthe tank body, and means mounted within said saddles for connecting saidtank body to said bolster and constructed and arranged to permitlongitudinal movement and prevent vertical movement of said tank bodyrelatively to said underframe.

7. In a tank car, a tank body, an underframe comprising a transversebolster, saddles mounted one on either endof the bolster for supportingthe tank body, members secured to the bolster inside of said saddles andcomprising upwardly extending spaced lugs, and members secured to saidtank body, and pivoted to said spaced lugs, the parts being constructedand arranged to permit movement of said tank body longitudinally of saidunderfralne and prevent vertical or transverse movement thereof. a

8. In a tank car, a tank body, an underframe comprising a transversebolster, saddles mounted one on either end of the bolster for supportingthe tank body, members secured to the bolster inside of said saddles andcomprising upwardly extending spaced lugs,'and members secured to saidtank body and provided with lugs extending between and pivoted to saidspaced lugs, a clearance being formed between said last-mentioned lugsand said upwardly extending lugs whereby the ends of said tank are freeto move longitudinally of said underframe, but are restrained frommoving transversely thereof.
